Dear Fran, We are thinking differently. In this case Piantelli obtains his nanoNi by a physical method method, Molecular Beam Epitaxy with the desired morphology and the active sites have to be made free, cleaned. . Not the case of partially damaged sites.
There are many physical and chemical processes of making nanoNI- perhaps Rossi has found a better one. Vacuum mills is an excellent idea in principle- how high a vacuum can be achieved and maintained? Alloys opens a new dimension, it is possible some will work better even than Ni- but only experiment can say. Re Cleaning I give you an example from my practice. Some acrylic monomers are extremely sensible to the presence of Sulphur compunds, even under 1 ppm. To determine analytically S is an ordeal. The engineers add a spoon of copper salt to the batch and S is fixed, harmless. Radical solution.
